In each instance, I had begun my adventure typing ping at command prompt interrogating the gateway, ultimately receiving the error “destination unreachable.” With each instance, I had gained a little bit more experience as Windows guy on UNIX. I had hoped summarizing those collective experiences in the steps below.

Additionally, I had thought to iterate having the proper VLANs configured in VMWare guest settings and any attached network equipment. So, if you had received “destination unreachable” when pinging your gateway begin with the below:
